CCGT04T004L-F NX2525
Swiss-Lathe Specialist | NX2525 Cermet Grade | 0.4mm Radius
Technical Breakdown
NX2525 Grade (TiCN Cermet): This Titanium Carbonitride-based cermet is designed for high-speed finishing. Unlike standard carbide, the NX2525 cermet has a very low chemical affinity for steel, which prevents Built-Up Edge (BUE). This allows for significantly higher cutting speeds and results in a glossy, mirror-like surface finish.
L-F Chipbreaker (Left-Hand Finishing): Specifically designed for miniature workpieces and Swiss lathes. The L-F geometry features a ground-in sharp edge that excels at ultra-light Depths of Cut (DOC). The 0.4mm radius provides superior edge strength for continuous finishing cycles.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCGT04T004L-F | 4.76 mm | 3.97 mm | 0.40 mm |
| Imperial | CCGT1.5(1.2)1L-F | 0.187" (3/16") | 0.156" (5/32") | 0.0157" (1/64") |
Recommended Cutting Parameters
*The 0.4mm radius allows for slightly higher feed rates than the 0.2mm version while maintaining surface integrity.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Mild & Carbon Steel | 180 - 320 m/min | 0.05 - 0.15 mm/r | 0.05 - 0.60 mm |
| Alloy Steel (Hardened) | 120 - 220 m/min | 0.05 - 0.12 mm/r | 0.05 - 0.45 mm |

NX2525 (Cermet): This is your "Shine" specialist. Ideal for high-speed, continuous finishing where appearance and dimensional accuracy are paramount.
VP15TF (PVD Carbide): Switch to VP15TF if you encounter interrupted cuts, vibration, or are machining gummy 300-series Stainless Steels. Carbide is tougher and prevents the edge from chipping in unstable conditions.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
